Subject: [SPARC64]: Disable IRQ forwarding.
X-Git-Tag: v2.6.12-rc4~117^2~21
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=41832a08feca695158e15a6e58c26b224a7bfae2;p=linux-2.6

[SPARC64]: Disable IRQ forwarding.

There is some race whereby IRQs get stuck, the IRQ status
is pending but no processor actually handles the IRQ vector
and thus the interrupt.

This is a temporary workaround.
